8305383989 sw_engine: optimize 64-bit rasterization. 
Write the pixels per 64-bit data.
This optimization can potentially double the performance in the best case scenario.
It's visually noticeable, especially when the resolution is sufficiently large.

21c7debf14 composite: Support Inverse Luma Masking 
The CompositeMethod now includes the newly supported InvLumaMask option:

The source pixels are converted to grayscale (luma values),
and the complement of the target's pixels is alpha blended.
As a result, only the part of the source where the grayscale
is not covered by the target is visible.

@APIs: CompositeMethod::InvLumaMask

@Example: examples/InvLumaMasking.cpp

3dd65dfed0 common picture: support image mesh feature 
Tvg Picture newly provides mesh() api to support texture mapping.
These apis allows to have a coarse triangle list which have polygon coordinates
and texture uvs those are used for traditional polygon texture mapping.

Note that these apis are beta version.

@API Additions:

Result mesh(const Polygon* triangles, const uint32_t triangleCount) noexcept
uint32_t mesh(const Polygon** triangles) const noexcept

@Examples:

//Mapping with two polygons
Polygon polygon[2];

//First polygon
polygon[0].vertex[0].pt = {0, 0};
polygon[0].vertex[1].pt = {100, 0};
polygon[0].vertex[2].pt = {0, 100};
polygon[0].vertex[0].uv = {0, 0};
polygon[0].vertex[1].uv = {1, 0};
polygon[0].vertex[2].uv = {0, 1};

//Second polygon
polygon[1].vertex[0].pt = {100, 0};
polygon[1].vertex[1].pt = {100, 100};
polygon[1].vertex[2].pt = {0, 100};
polygon[1].vertex[0].uv = {1, 0};
polygon[1].vertex[1].uv = {1, 1};
polygon[1].vertex[2].uv = {0, 1};

//Apply polygons to the picture
picture->mesh(polygon, 2);

4cbeb5e3df compositeMethod: introduced LumaMask 
Introduced CompositeMethod::LumaMask that converts the source pixels to the
grayscale (luma value) before alpha blending. Thanks to it, mask works more like
typical mask in graphics editor software.
Grayscale is calculated with  weighted method:
(0.0721*B + 0.7154*G + 0.2125*R) * A
Introduced surface->blender.lumaValue function
